To all whom it may concern: p Y

Be it known that I, Anrmm STANLEY Qrncx, a subject of the Kingdom of Great Britain, residing at London, Southwest, I Engand, have invented certain new anduseful' mprovements in Oils for which I have made application in England, March 20, 1920 Patent No. 161,- 8 13; and I do hereb to a full, clear, an exact. descri tion 0 the invention, such-as 'will enab e others skilled in the art to which it appertains' to make and use the same.

This invention relates to the refining of gallons commercial linseed oil are laced in a pan .to which are added 20 gal- 80 one water and 10- lbs. of monazite sand. The contents of the pan are heated to about 120 F. and air is blown in to break against the bottom of the pan'and ascend in bubbles from the sand through the water and I 86 the oil. I continue this treatment forabout six hours, and then allow the oil to stand for. another four hours when the foots etc., separate, leaving the oil clear, and in non- -breaking condition. The water is then separated in known manner. The monazite sand canbe used repeatedly. In general a temperature of 120 F. may be used for most oils. The temperature a Process of Refining declare the followin adding to every employed may be slightly higher long as the tem erature is not raised suiiiciently 45 high to e ect any deleterious chemical or physical change in the oil. A lower temperature may also be used, but with a lower temperature the stirring treatment will reuire to be continued for a longer period. or instance, if a tem erature of 100 F.

were employed the stirring treatment should be continued for between seven and eight hours.

As a result of experimental research I 66 have ascertained that the refinement obtainable by my process is not obtainable by the substitution for monazite sand of oxides usually regarded as catalysts and that again such refinement is not obtainable by the use 60 of organic absorbent such as fullers earth. Hence I conclude that the refinement is effected by radio activity which within the ran of temperatures contemplated and int e presence of water exercises a definite 05 action on the foots without producing any chemical or physical change in the oil, as a result of which the foots separate of themselves when the mixture is allowed to settle.

I claim 70 1. A process of refining oil consisting in addin to the oil an equal quantity of water and a ut one half the quantityof monazite sand, heating the mixture, stirring the mixture, allowing the mixture to settle and then separating the oil.

2. A process of refining oil consisting in 20 gallons of the oil an equal quantity ofwater and 10 lbs. of monazite sand, heating the mixture to about F. and stirring for approximately six hours, allowing to settle for four hours and then separating the oil in known manner. In testimony whereof I have signed my name to this specification.
